My friend, Im afraid you have gotten a bit overboard with the project. You have purchased a kill gillion parts and spent alot of money on things, and you want a nicely restored car no doubt. But this being said, Im afraid you are spending far to many dollars for a project that will fail to be worth the money you have in it. Surely the car isnt so rusted, in such bad shape you need to resort in such an extreme solution. Media blast, or soda blast or something, but in cases of the guy who "wants to overrestore their car" beyond reason, body shop guys love to find people I fear such as yourself. These guys dont do insurance work, they specialize in GRINDING on guys who want their cars to be max nice. If you have the money, they can find the solution. The idea of cutting a car in half is ultra extreme. For goodness sake remember in the long run its a 383 car. Dont end up with $60K in a $35k car. Nothing wrong with wanting a nicely done car, but remember more than likely this car is gonna sit inside, not driven in bad wearther, and well kept. Its not gonna rust back up on you in a few years.
